Head and Neck Sinus and Mass

Abstract

Cervical mass and sinus of the neck represent a wide variety of anomalies, both congenital and acquired. Each branchial arch and its components can be traced to the formation of future anatomic structures. The most common lesions arise from the thyroglossal duct or branchial structures, particularly from the second branchial cleft. The third and fourth clefts form the pharynx below the hyoid bone and these anomalies from these clefts enter into the pyriform sinus. In general, thyroglossal duct or cyst lesions lie close to the midline, whereas branchial remnants present more laterally in the neck.
